This is the unabridged audio version of the book that, for some reason, is impossible to find anymore (out of print?). I bought it along with the (also excellent) study guide. Dr. Kennedy takes you step by step through 18 topics that are critical for (as R.C. Sproul would say) "Getting The Gospel Right". I must warn you, these are not simplified overviews and the material is decidedly reformed in perspective. You will be challenged to dig deeper into topics you USED TO THINK were splitting hairs and at times you will feel like you signed up for a seminary course - but your reward is well worth it - a clear understanding of these transformational truths!
